soc: qcom: qmi_interface: Limit txn ids to U16_MAX

2018-11-14T18:02:07+00:00

Txn IDs created up to INT_MAX cause overflow while storing
the IDs in u16 type supported by QMI header.

Limit the txn IDs max value to U16_MAX to avoid overflow.

drivers: edac: Add EDAC driver support for QCOM SoCs

2018-09-13T20:54:05+00:00

Add error reporting driver for Single Bit Errors (SBEs) and Double Bit
Errors (DBEs). As of now, this driver supports error reporting for
Last Level Cache Controller (LLCC) of Tag RAM and Data RAM. Interrupts
are triggered when the errors happen in the cache, the driver handles
those interrupts and dumps the syndrome registers.

soc: qcom: Add support to register LLCC EDAC driver

2018-09-13T20:53:58+00:00

Cache error reporting controller detects and reports single and
double bit errors on Last Level Cache Controller (LLCC) cache.
Add required support to register LLCC EDAC driver as platform driver,
from LLCC driver.

soc: qcom: Add broadcast base for Last Level Cache Controller (LLCC)

2018-09-13T20:53:51+00:00

Currently, broadcast base is set to end of the LLCC banks, which may
not be correct always. As the number of banks may vary for each chipset
and the broadcast base could be at a different address as well. This info
depends on the chipset, so get the broadcast base info from the device
tree (DT). Add broadcast base in LLCC driver and use this for broadcast
writes.

drivers: soc: Add LLCC driver

2018-07-21T18:31:35+00:00

LLCC (Last Level Cache Controller) provides additional cache memory
in the system. LLCC is partitioned into multiple slices and each
slice gets its own priority, size, ID and other config parameters.
LLCC driver programs these parameters for each slice. Clients that
are assigned to use LLCC need to get information such size & ID of the
slice they get and activate or deactivate the slice as needed. LLCC driver
provides API for the clients to perform these operations.

qcom_mdt_load function loads the mdt type firmware and

when requested by the caller, so that the function can be used
by self-authenticating remoteproc as well.

Pull ARM SoC late updates from Olof Johansson:
 "This is a branch with a few merge requests that either came in late,
  or took a while longer for us to review and merge than usual and thus
  cut it a bit close to the merge window. We stage them in a separate
  branch and if things look good, we still send them up -- and that's
  the case here.

  This is mostly DT additions for Renesas platforms, adding IP block
  descriptions for existing and new SoCs.

  There are also some driver updates for Qualcomm platforms for SMEM/QMI
  and GENI, which is their generalized serial protocol interface"
